First, grape winter pruning 1, winter cut time buried area is generally appropriate in mid-late October, completed before the cold freeze injury, in order to facilitate the next frame buried. 2. Pruning method (1) Short cut: Cut a year old branch to a part, according to the length of the remaining branches can be divided into long tip pruning (leaving 8-12 buds); middle tip pruning (leaving 5-7 buds); short Tip trimming (leaving 1-4 buds). (2) Thinning: Exclude the dense branches from renting pests and branches. (3) Retraction: The branches of 2 years old or older are cut to the branches or 1 year old branches, and the tree potential is updated and adjusted. Second, branch renewal After investigation, the vine in our district is more than 7 years of age, the results of the site gradually move up, the lower part of the bald and neutral, therefore, the mother of the results to be updated rejuvenation. 1. Two-branch update: One cut length, one cut-off, long-lasting result mother branch, next year's result, after cut off; short later, make the preparation branch next year branch, winter cut and cut again Long stay short update. 2, single branch update: In the main branches of vines on the sparsely populated, the selection of well-grown mature shoots tip trim, updated after the results of the following year. 3, Dulong plastic: Mainly applies to a dragon tree shape, from the young age on the attention of tree-shaped culture, starting from the grape base 50-60cm, every 20cm or so, leaving a result site, the remaining sparse, according to the age of tree potential Each year, the ear is carefully selected and the refinement is not required. When the winter shear is used, short shoots are trimmed (leaving 1-4 buds), so that the selected result area becomes a permanent result, and the resulting parts are pruned each year to form a claw shape. Third, clean garden disinfection after the winter cut before the buried, the park dead branches, rotten leaves, weeds were burned, and 50% carbendazim WP 800 times the entire garden spray disinfection. Fourth, buried in cold weather generally requires timely burial in soil before freezing, buried soil moisture should not be too large, to prevent the growth of pathogens infested branches and buds, if buried too late grape exposure to cold branches frozen, will result in reduced yield ( Xinjiang Dongjiang District is particularly noticeable. At the same time, the soil is not well-frozen. Even if it is buried, the frozen soil blocks are not easily compacted and affect the buried effect. 1, buried method: (1) younger vineyard branches softer, easy operation, do not dig trenches on the ground directly buried. (2) Due to the age of the age-old vines, the grown-up vineyards are not easy to bend. Generally, the ditch is buried and the 30cm soil pillow is first cultivated around the bend of the main vine root to prevent the branches from breaking when they fall off the shelf. Put the branches along the ditch and put it into the grape ditch. Cover it with 10-15cm straw or leaves, and sprinkle some poison baits to prevent rat damage. Then use the earth to prevent cold and cover soil with a thickness of 30cm or more. Fifth, the following year, withdraw from the soil, and open the pier in East Xinjiang area, generally in mid-April to withdraw soil and open the pier. After opening the pier, germinate with 50% of Solibal WP 100% liquid before gardening to prevent powdery mildew. Early removal of cold-proof materials, unstable temperatures, hot and cold, affecting the growth of grapes, while spreading the soil too early to low temperatures, weak root activity, poor absorption capacity, resulting in insufficient supply of shoot water, resulting in dry phenomenon; If soil is too late, soil temperature rises and mildew or winter buds germinate. When the shelf hits and affects the yield, each management stage of the grape cannot be taken lightly. Only in this way can the high yield and stable production of the grape be guaranteed.
